我正在尝试运行这个项目,我在 sbt 文件中添加了依赖项,我的 sbt 文件如下所示:name := "HelloScala"version := "0.1"scalaVersion := "2.11.8"libraryDependencies += "org.apache.spark" %% "spark-core" % "2.3.1"resolvers += Resolver.bintrayRepo("salesforce", "maven")libraryDependencies += "com.salesforce.transmogrifai" %% "transmogrifai-core" % "0.3.4"然后我Helloworld从他们的存储库中复制了该文件夹,但有很多问题。Information:10/09/18, 12:01 PM - Compilation completed with 88 errors and 0 warnings in 15 s 624 msError:scalac: missing or invalid dependency detected while loading class file 'package.class'.Could not access type Vector in value org.apache.spark.ml.linalg,because it (or its dependencies) are missing. Check your build definition formissing or conflicting dependencies. (Re-run with `-Ylog-classpath` to see the problematic classpath.)A full rebuild may help if 'package.class' was compiled against an incompatible version of org.apache.spark.ml.linalg.Error:scalac: missing or invalid dependency detected while loading class file 'OPVector.class'.Could not access type Vector in value org.apache.spark.ml.linalg,because it (or its dependencies) are missing.

在build.sbt两个依赖是缺失的:spark-mllib和spark-sql
libraryDependencies ++= Seq(
"org.apache.spark" %% "spark-core" % "2.3.1",
"org.apache.spark" %% "spark-mllib" % "2.3.1",
"org.apache.spark" %% "spark-sql" % "2.3.1",
"com.salesforce.transmogrifai" %% "transmogrifai-core" % "0.3.4"
)
这将删除第一个错误块。
